GROUND-BASED CHARACTERIZATION OF THE EDDINGTON PLANET FINDING FIELD

摘要

In this paper we discuss the observations needed for the ground-based characterization of the Eddington Planet Find Field (EPFF). Ground-based characterization is necessary in order to successfully plan the observations of Eddington, The limited telemetry available from the spacecraft imposes an a priori selection of the targets to be photometrically monitored. An appropriate characterization allows to define the optimal temporal sampling of the targets for the planet transit search, and to identify targets for asteroseismology and parallel science studies. The amount of ground-based data to be collected, and the corresponding huge amount of reduction and analysis work, imposes an immediate start of the characterization program.
